Aliases:

Converts each string in the input Tensor to its hash mod by a number of buckets.

The hash function is deterministic on the content of the string within the
process. The hash function is a keyed hash function, where attribute key
defines the key of the hash function. key is an array of 2 elements.

A strong hash is important when inputs may be malicious, e.g. URLs with
additional components. Adversaries could try to make their inputs hash to the
same bucket for a denial-of-service attack or to skew the results. A strong
hash prevents this by making it difficult, if not infeasible, to compute inputs
that hash to the same bucket. This comes at a cost of roughly 4x higher compute
time than tf.string_to_hash_bucket_fast.

Args:

input: A Tensor of type string. The strings to assign a hash bucket.

num_buckets: An int that is >= 1. The number of buckets.

key: A list of ints.
The key for the keyed hash function passed as a list of two uint64
elements.
